电子密码锁程序，两键输入，其中一个键累加，另一个键确认。密码正确锁打开（开锁指示灯亮）；密码错误锁关闭（关锁指示灯亮）；连续错三次则锁定键盘8秒并发出报警声。-Electronic code lock procedure, the two key input, one key additive, and the other button to confirm. The correct password to open lock (unlock indicator light) password error lock closure (Kuan-lock indicator light) consecutive wrong then lock the keyboard three times and issued eight seconds alarm sound.

DS18S20是一种典型的1-Wire总线接口温度传感器，由Dallas Semiconductor公司生产。DS18S20数字温度传感器提供了9位高精度的摄氏温度测量，同时具有非易失性、用户可编程上下触发门限的报警功能。由于其独特的1-Wire总线接口，使得其可以占用极少的I/O引脚资源，使用起来十分方便-DS18S20 is a typical 1-Wire bus interface, temperature sensor, manufactured by Dallas Semiconductor. DS18S20 digital temperature sensor provides high-precision 9 Celsius temperature measurement, both non-volatile, user-programmable upper and lower trigger threshold alarm. Because of its unique 1-Wire bus interface, making it can take up very little I/O pin resources, is very convenient to use

尽量朝“单片”方向设计硬件系统。系统器件越多，器件之间相互干扰也越强，功耗也增大，也不可避免地降低了系统的稳定性。随着单片机片内集成的功能越来越强，真正的片上系统SoC已经可以实现，如ST公司新近推出的μPSD32××系列产品在一块芯片上集成了80C32核、大容量FLASH存储器、SRAM、A/D、I/O、两个串口、看门狗、上电复位电路等等。 -North Korea as the "single-chip" design direction of the hardware system. System devices more mutual interference between devices are more strong, power consumption is increased, it will inevitably reduce system stability. With MCU with on-chip integration of more powerful, the real system-on-chip SoC can achieve, such as ST"s new PSD32 x x in a series chip integrates exertion nuclear, large-capacity flash memory, SRAM, A/D, I/O, 2 serial port, watchdog, the power-on reset circuit and so on.
